piezo electric painkiller?

This summer my mother has decided that cure is better than prevention for insect bites.
She has a small device like a gas lighter that uses a peizo electric crystal to cause a small spark like a gas lighter but it is positioned so that when pushed against your skin it causes a small jolt. This she claims takes away the sting of an insect bite. I’ve tried it and it does cause a small electric jolt but I don’t know about how it could cure an insect sting whether it stops pain or otherwise. Could it work?
